TheV drawings do not`show lthese screws asn holding the work but that will `be obvious.

i VAs yso far described, the jaws 26 can be tipped up about the longitudinal axis only,

i to such `position as is possible dueto the limitation of the flangev 2O at the bottom.

lIn this case two jaws 47 and 48 are mounted on the jawlsupport in a manner such as other'. This enables the support 46 to swing f approximately 90 degrees about the bolt 43.

It will be seen that in both constructions,

ai very wide degree of adjustment is secured inl a very simple manner and in fact the ad-k justment is practically universal and yet the y* mechanism is simple and inexpensive; The

adjustments are made easily and yany die sinker will Vbe kable ,to understand the vmachine ywithoutany trouble. i
